Many species of orchids in fragmented landscapes need active management to secure their persistence. The effects of fragmentation can be direct (e.g. reduction in population sizes, environmental quality, increased inbreeding, reduced dispersal ability), or indirect through negative effects on pollinators. Little information exists on the complex interactions between effects of fragmentation on plants and their pollinators. This project aims to understand how fragmentation affects the genetic diversity and demography of selected populations of orchids and their pollinators in the Mt.Lofty/Flerieu Peninsula area. This information will help to develop and implement more effective conservation plans.

碎片景观中的许多兰花需要积极的管理以确保其持久性。分裂的影响可以是直接的（例如，人口量减少，环境质量，增加的繁殖，降低的分散能力），或通过对授粉媒介的负面影响间接的。关于破碎对植物及其传粉媒介的影响之间的复杂相互作用的信息很少。该项目旨在了解破碎化如何影响兰花及其传粉媒介在Mt.lofty/Flerieu Peninsula地区的遗传多样性和人口统计学。这些信息将有助于制定和实施更有效的保护计划。
